I am trying to model the flow fields of magnetorheological fluid between non-magnetic parallel plate and permanent magnets under magnetic field produced by permanent magnets in in COMSOL3.5a.
There are two permanent magnets and three non-magnetic parallel plates in the model. The middle plate can move in the x direction at a speed of 0.025m/s. The gaps between two permanent magnets and the middle plate are filled with magnetorheological fluid.
There are adhesive forces between the magnetorheological fluid and the middle plate, so magnetorheological fluid can moves with the middle plate. The magnetostatics, Moving Mesh (ALE) and Non-Newtonian Flow modules have been chosen in my model. I have got the magnetostatic field simulation results which can be used as the initial values to deal with the flow fields.
But I do not know how to deal with the flow fields simulation due to the adhesive forces.
Could anyone give me any hint about this, it would be highly appreciated.
Regards,
Hongliang
